2008-07-13 Christian Neumair <cneumair@gnome.org> * libnautilus-private/nautilus-dnd.c (nautilus_drag_uri_array_from_selection_list), (nautilus_drag_uri_list_from_selection_list), (nautilus_drag_uri_array_from_list), (nautilus_drag_uri_list_from_array), (slot_proxy_drag_motion), (drag_info_clear), (slot_proxy_drag_leave), (slot_proxy_drag_drop), (slot_proxy_handle_drop), (slot_proxy_drag_data_received), (nautilus_drag_slot_proxy_init): * libnautilus-private/nautilus-dnd.h: Add simple slot drop proxy API to libnautilus-private, centered around nautilus_drag_slot_proxy_init(). The notebook tab label drop targets will later be ported to this API. Add API for converting URI lists to URI arrays, and for constructing URI lists and arrays from selection lists. * src/nautilus-notebook.c (notebook_tab_drag_data_received): Use nautilus_drag_uri_array_from_selection_list(). * src/nautilus-pathbar.c (slider_timeout), (nautilus_path_bar_slider_drag_motion), (nautilus_path_bar_slider_drag_leave), (nautilus_path_bar_init), (nautilus_path_bar_finalize), (button_data_free), (button_drag_data_get_cb), (setup_button_drag_source), (make_directory_button): * src/nautilus-pathbar.h: Add path bar drop targets, use nautilus_drag_slot_proxy_init() for setup. Also offer GNOME icon lists as drag target. Reveal hidden paths when hovering over the up/down sliders for some time. Fixes #309842. svn path=/trunk/; revision=14356
